Abstract

The increasing demand for sustainable materials has intensified interest in alternative strategies for non-wood biomass such as bamboo. In this study, a glycol ether-based organosolv pulping process was investigated to evaluate the influence of reaction conditions and pulping liquor composition on the properties of bamboo pulp. The results showed that this led to significant screened yield loss and the production of fines (>0.2 mm) under excessively harsh conditions. Mild temperature conditions (100°C) preserved fiber length and strength, resulting in improved papermaking performance. The dissolution yield increased with increasing reaction temperature, reaction time, and chemical severity (Glycol ether ≥ 95% and catalyst ≥ 0.6 M), indicating that such conditions are suitable for fabricating dissolution-grade bamboo pulp. Based on these results, it is confirmed that the properties of bamboo pulp can be effectively adjusted by controlling both the reaction conditions and the composition of the pulping liquor. The glycol ether-based organosolv pulping process provides fundamental data for selectively producing either paper-grade or dissolution-grade bamboo pulp, depending on the targeted end use.
